A U-shaped blanking frame 7 is provided above the bottom plate 1, and two connecting plates 6 are fixed on both sides of the U-shaped blanking frame 7. The top ends of the vibration springs 5 are fixed to the bottom surfaces of the connecting plates 6, and vibration motors 2 are fixed on both sides of the U-shaped blanking frame 7. The utility model also includes:

[0024] The screen 8 is arranged inside the U-shaped blanking frame 7. The lower ends of the inner walls of the U-shaped blanking frame 7 are provided with limiting chutes 23. The two sides of the screen 8 are slidably connected to the inner walls of the limiting chutes 23. The inner wall of the U-shaped blanking frame 7 is fixed with multiple support rods 24 that cooperate with the screen 8. Two symmetrically distributed rectangular blocks 11 are fixed on one side of the screen 8. A limiting mechanism is provided on one side of the U-shaped blanking frame 7 corresponding to the rectangular blocks 11.

[0025] It is worth noting that by starting the vibration motor 2, the U-shaped discharge frame 7 vibrates with the cooperation of the vibration spring 5, thereby driving the screen 8 to screen the ore, wherein multiple support rods 24 support the screen 8, thereby improving the stability of the screen 8 in the limiting chute 23.

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the limiting mechanism includes a mounting block 15 fixed to the outer surface of the U-shaped blanking frame 7, and a push rod 17 is movably passed through the top surface of the mounting block 15, and a connecting rod 13 is fixed to the bottom end of the push rod 17. Two symmetrically distributed insertion rods 12 are fixed on one side of the connecting rod 13, and the two insertion rods 12 are movably passed through the rectangular block 11 respectively. A limiting spring 16 is sleeved on the outer surface of the push rod 17, and the top end of the limiting spring 16 is fixed to the bottom surface of the mounting block 15, and the bottom end of the limiting spring 16 is fixed to the top surface of the connecting rod 13. A clamping part is provided on the top of the push rod 17.

[0027] Further as Figure 2 As shown, it is worth mentioning that the clamping part includes a U-shaped connecting block 18 fixed to the top of the push rod 17, the inner side of the U-shaped connecting block 18 is rotatably connected to a rotating rod 20, the top of the rotating rod 20 is fixed with a rectangular ring 22, and the outer surface of the U-shaped blanking frame 7 is fixed with an L-shaped clamping rod 21, and the rectangular ring 22 is clamped with the L-shaped clamping rod 21.

[0028] Further as Figure 2 As shown, it is worth mentioning that a pull ring 19 is fixed on one side of the rotating rod 20, which facilitates the movement of the rotating rod 20 and brings convenience to the staff's operation; a grip ring is fixed on one side of the screen 8, which facilitates the holding of the screen 8.

[0029] Further as Figure 2 As shown, it is worth mentioning that two symmetrically distributed protrusions 27 are fixed on the side of the connecting rod 13 away from the U-shaped blanking frame 7, and two symmetrically distributed fixed blocks 25 are fixed on the outer surface of the U-shaped blanking frame 7. A limiting rod 26 is fixed to the bottom surface of the fixed block 25, and the limiting rod 26 is movable through the protrusion 27. When the connecting rod 13 moves up and down, it drives the protrusion 27 to slide on the limiting rod 26, thereby limiting the connecting rod 13 and improving the stability of the push rod 17 during its movement.

[0030] Further as Figure 1 and Figure 4As shown, it is worth mentioning that arc-shaped guard plates 3 cooperating with the vibration motor 2 are fixed on both sides of the U-shaped blanking frame 7, and the arc-shaped guard plates 3 are used to protect the vibration motor 2 to prevent the vibration motor 2 from being bumped; the top surface of the bottom plate 1 is slidably connected to the screen 8 with a collecting frame 14, which facilitates the collection of the ore that has fallen after screening through the collecting frame 14; a mounting frame 10 is fixed on the inner side of the U-shaped blanking frame 7, and a feed hopper 9 is fixed on the inner side of the mounting frame 10, which facilitates the ore to fall into the U-shaped blanking frame 7 through the feed hopper 9.

[0031] This solution has the following working process: the U-shaped blanking frame 7 is vibrated by the vibration motor 2 and the vibration spring 5, so that the screen 8 vibrates and screens the ore, wherein the screen 8 is easily contaminated by impurities after a long time, and the ore is easy to cause wear to the screen 8, thereby causing damage to the screen 8. By holding the pull ring 19, the rotating rod 20 is lifted upward, thereby driving the rectangular ring 22 to move upward, and then rotating the rotating rod 20 so that the rectangular ring 22 is stuck on the L-shaped clamping rod 21. At this time, the push rod 17 drives the insertion rod 12 to disengage from the rectangular ring 22, and then pulls the screen 8 out of the limiting slide groove 23, so as to facilitate the replacement of the screen 8. After replacing the new screen 8, the rotating rod 20 is moved upward so that the rectangular ring 22 is disengaged from the L-shaped clamping rod 21, and then under the elastic force of the limit spring 16, the push rod 17 pushes the connecting rod 13 downward, so that the insertion rod 12 passes through the rectangular block 11, thereby limiting the screen 8.

[0032] According to the above working process, it can be seen that: through the setting of the limiting mechanism, the function of convenient disassembly and assembly of the screen 8 is realized, which provides convenience for the operation of the staff. Through the cooperation of the clamping part and the limiting mechanism, the rectangular ring 22 can be clamped on the L-shaped clamping rod 21 during the disassembly and assembly process, thereby maintaining the stability of the push rod 17, further facilitating the operation of the staff.
